CAUTION
• The power supply cables must be connected to R, S, T. If they are connected to
U, V, W, the inverter will be damaged. (Phase sequence need not be matched.)
• Connect the motor to U, V, W.
Turning on the forward rotation switch (signal) at this time rotates the motor
counterclockwise when viewed from the load shaft.
